Little is officially known about the upcoming X-Men: Apocalypse, which was announced two weeks ago, but thanks to director Bryan Singer we now have an idea of who is behind the scenes for the sequel. Singer tweeted about a “Late night X-Men Apocalypse story session” last night and the photo included not only Singer and X-Men: Days of Future Past screenwriter Simon Kinberg, but also X2: X-Men United screenwriters Mike Dougherty and Dan Harris! This marks the first time since “X2” that Dougherty and Harris have worked on an X-Men film. Though it remains to be seen who will officially pen the screenplay for the sequel, it’s certainly exciting to see former franchise writers return to the series.

In addition, Singer added “It’s snowing in Egypt!” to his tweet, which might seem unrelated but Egypt was in fact the birth place of Apocalypse/En Sabah Nur’s in the original source material.

Created by Louise and Walter Simonson, Apocalypse made his debut in X-Factor #6. The character’s most popular storyline, “The Age of Apocalypse,” ran in the X-Men books beginning in 1995. Set in a parallel reality formed by interference to the timeline, “The Age of Apocalypse” saw Professor Charles Xavier murdered before he could form the X-Men. Instead, a very different take on the team began with Magneto leading them through a post-apocalyptic America ruled by mutants.
